Beams 3sge + ST205 CT20b = ?

[DeeCee]

Wondering if a st205 ct20b can be fitted to a beams 3sge in an altezza.

I have a manifold and ct20b turbo from a st205 and the ct20b needs a rebuild and i'm looking at a new car for myself anyway.

1. would the manifold bolt up or would something have to be made up for the application.

2. potential of a ct20b on a beams?

3. i assume aftermarket ecu.. suggestions?

cheers

1 - not sure if the factory manifold would bolt up, but it would position the turbo around the wrong way, and possibly quite a long way rearward, making the downpipe rather tight. a better designed exhaust manifold would be the go here.

2 - could be alright. beams 3sge head flows very well up high in the rev range, so the ct20b in stock form could choke it a bit.

3 - powerfc is the most cost effective option (as they make a plugin) i also know the new g3 linkplus will be able to handle vvt-i, but would require you to wire in. Greddy e-manage will also be able to handle it, but its a piggyback, not a stand alone ecu..

I disagree with this point.

I'd put good money on the beams popping before the ct20b not being able to feed it enough air.

With stock compression anyway. I'd imagine if you were to turbo one you'd at least use a thicker headgasket.

[DeeCee]

yep - will look at doing a thicker gasket to reduce compression

Thicker headgaskets do not reduce detonation.

i thought it did? meh - i know nothing - hence why i'm asking and talking and reading and researching

what you think sergei? ct20b on a beams 3s? or go larger
and i'll hit you back tonight with the carputer stuff - too busy last night

[sergei]

On stock beams? CT20b would be big enough. I think it actually will be too big.
But I tell you it will not last long.
You will need to lower compression substantionally (Thicker head gasket lowers compression but it does not reduce chance of detonation because it reduces swirl).

pwwwwrrr... psssttttt.... boooom! DOH!

well, there is always the option of supercharging.. which my friend and his dad are doing to their race car..

[strx7]

go the honda route, larger turbo, running less boost. higher compression will spool a larger turbo faster, and means more HP for the same PSI, or less boost for same HP than a lower compression engine.

[rollaholic]

you'll still want lower compression on a supercharged car

A friend of mine once had a civic with a GT35/40 on a B16A, ran low boost (i think it was around 9psi or something) but it made 200+wkw

so you think viable? or maybe just go to a td03/04?

My friend who is suprcharging his racecar showed me this just now.. i have no idea what portends

Its an expensive idea if you cant do the work your self. S15 Spec R would be cheaper.

[DeeCee]

well i would be doing as much work as i can myself.. the celica issue was to get engine rebuilt.. which i can't do myself, nor have the room to do it.

and i have guidance if i did want to do the altezza engine.. or i just buy woolly's car..

[Distrb]

or i just buy woolly's car..

much better idea!

[DeeCee]

but he wants mid 20's.. which is waaayyy out of my budget lol

[strx7]

so you think viable? or maybe just go to a td03/04?

I'd go with a 'medium' T04 or a TD06,

[Alex B]

To be honest if doing a rebuild is out of your leauge then so is turboing. To do it right you would want 3S-GTE pistons so thats pretty much a rebuild there. What would a good altezza cost? Say 15K?? Stand alone ECU Say a linkplus G3 with tuneing would be around the 3k mark, then upgrade brakes, fuel system, turbo, intercooler, pipeing, BOV, random other little bits. Makes mid 20's sounds a rather good deal for a turbo altezza.

[sergei]

In my opinion in the long run it would be cheaper to stick stock 2JZ-GTE in it, than turbo-ing BEAMS engine. It also would be nicer to drive.
Or even 1JZ-GTE, they are nice motors and are much cheaper than 2JZ-GTE.

Just a question here: Are we talking about Altezzas right?
If it is about BEAMS celica, than forget what I said above
